bopomofo teaches the 37 Bopomofo (Zhuyin) symbols that Taiwan uses to spell Mandarin, so you learn to read without pinyin. Draw each symbol and get stroke-order feedback. Record syllables and get a check on initials, finals, and tones. Train your ear on tones and tone changes. Bobo, the coach, reads your practice stats, picks your next drill, and tells you why. Free and open source (AGPL-3.0).

Partial The UI and audio playback are straightforward, but evaluating stroke-order vector accuracy and performing speech recognition tone/phoneme analysis on Mandarin syllables requires specialized ML models.
What it would actually take: Requires a mobile/web framework with dynamic vector canvas stroke-matching algorithms (DTW or custom handwriting recognition models) and a specialized ASR pipeline capable of phoneme- and tone-level forced alignment for Mandarin. Off-the-shelf speech APIs rarely grade granular tone pitch contours accurately, so custom pitch-tracking (F0 contour extraction) or fine-tuned acoustic models are needed. Requires expertise in speech signal processing and Chinese phonetics.
